The poem "Yan Yan" has four chapters. The first three chapters focus on the scene of farewell, and the last chapter affectionately recalls the virtues of the person being sent away. The lyrics are profound and the language is painful, and the writing is vivid and respectful.
The first three chapters begin with the story of the flying swallow: "The swallow is flying, and its feathers are missing." "Zhu Zi Yu Lei" praised: "Just like a painter, he writes with great energy." In March of spring, swallows are flying, jumping up and down, and singing. However, the poet's intention is not just to depict a "picture of a spring swallow's test flight". Instead, the freedom and joy of Yanyan flying together contrast with the sorrow and sadness of the separation of compatriots. This so-called "like a painter" also "writes out the spirit". Then he pointed out the reason: "When my son returns home, I send him away to the wild." His father has passed away, his sister is going to marry far away, and the brothers and sisters are separated today. It is difficult to say goodbye in this situation. "Farther than I will send you", "far away to the south", sending each other off one way after another, and the sadness of separation can be seen even more. However, even when we see each other thousands of miles away, there is always a difference. The sister who married far away finally passed away suddenly, but the affectionate brother was still reluctant to leave. The poems here use artistic techniques to express touching situations: "looking beyond reach, weeping like rain", "standing still and weeping", "working hard on my heart". First, I climbed up to take a look. Although I couldn't see the carriages and horses, the dust was rising from time to time. Then, I couldn't see it, so I just stood there and wept, thinking sadly. The love between brother and sister is really deep, and they part ways with each other, which is so touching and sad that ghosts and gods can weep. These three chapters are sung repeatedly, which is easy to express the meaning of the poem, and also progresses step by step, and the music and scenery contrast with the sadness; thus, the farewell situation and the atmosphere of farewell are expressed in a profound and painful way, which makes it difficult to bear to finish reading.
The four chapters are from fiction to reality, translating the person who was sent away. It turns out that the second sister is extraordinary. She has practical and profound thoughts, a gentle and respectful temperament, a cautious and kind person, and is a good helper for him to govern the country. She held hands to say goodbye, but did not forget to give her words of encouragement: Don't forget the late king's instructions and become a good king for the people. This chapter of writing reflects the ancient ancestors' high evaluation of female virtues. In terms of writing method, first summarize the description, and then write the characters' language; there is movement in the silence, and the image is vivid. The four chapters are also very particular about the structure of the whole article. The first three chapters use virtual writing to exaggerate the atmosphere of farewell, while the last chapter uses real writing to depict the person being sent away, using an inversion method similar to "Zhaonan·Cai_".
After "Yan Yan", "Looking beyond reach" and "Standing and weeping" have become archetypal images expressing farewell situations, and have appeared repeatedly in farewell poems of all dynasties. The "tears" of "standing and weeping" have become one of the artistic images on which the theme of separation is based.
